Symptom

When the System Center Configuration Manager site server is running Windows Server 2008, installations, or upgrades of Configuration Manager current branch (versions 1511 – 1610) and long term servicing branch (version 1606) will fail to download and verify two required dependencies, resulting in overall setup failure.

The following errors are logged the setup.log file when the problem occurs:

Cause

This occurs because these SQL Server redistributable files (SQLSysClrTypes.msi and SharedManagementObjects.msi) have been signed with the SHA-256 digest algorithm.Windows Server 2008 does not support SHA-2 signing﻿﻿ which causes verification failure.

Resolution

The Configuration Manager site server needs to run a version of Windows Server that does support SHA-2 signing.
